Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed February 18,1907. Serial No. 358,127.

VTo all whom 'it muy concern:

Be it known that l, Anotrrros DAMERON, a citizen oi': the United States, residing at Maysville, in the county of Banks and State of Georgia, have invented. certain new'and useful Improvements in Auto1nobilo-lires, of which the following is a specification,

This invention has for its object an improved construction of resilient tire for automobiles or other ve;-

-tails of construction of the means for effecting the result, reference is to b e had to the following description and accompanying drawings, in -which:

Figure lisa transverse sectional view oi a tire enibodying features of my invention; Fig. 2 is a longitudinal sectional view of a portion o the tire, Fig. 3 is a detail transverse sectional view: Fig. 4 is a side elevation of the completed tire, parts being broken away;

Fig. 5 is a detail View illustratiuga portion of one o' the attachment rings; and, Fig. 6 is a detail perspective view of a portion of the steel band employed.

Corresponding and like 'parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing; the numeral 1 designates the 'inner pneumatic tube of my improved tire, slid tube being protected or inclosed'within a tread protective covering which includes an inner ply 2 of leather or similar tenacious and exible material, an outer ply 3 which is stitched, as indicated at 4 to the inner ply (the latter extending at its innermost edges beyond the outer ply asindicated at 2t), and band 5 of spring steel, or other impenetrable metal or material held between the said two plies 2 and 3. The band 5 is -transversel, slit and is curved in. cross section, as shown, and the ends 6 of said band overlap each other vlongitudinally and are tapered, as clearly illustrated in the drawing. To one overlapping end 6 a wear plate 7of highly polished or smoothed brass is secured in any l desired manner, while to the opposing face of the other to this end the protective covering formed by the plies 2 and 3, which incsses the entire band, is provided with a circumfercntinlly extending side slit 9 through which the lubricant may be inserted, when the tire is deflated.

Outside o the protective cover is the outer member of the tire'which is designated 10 und which is, as shown, ofthe Clencher type in the present instance, l eing composed oi rubber with any desired design of tread, and preferably embodying one er more embedded layers o1' canvas or similar textile fabric. The

edges l1 of the outer member project outwardly or are formed with the usual clencher [langes for attachment to the metallic rim 12. In the present instance, the

rim l2 is provided at its side edges with outwardly 'acing in vetted U-shaped flanges 13 producing sockets 14 adapted to receive the two attachment rings l5. The

attachment rings 15 are in the Aform of split rings, provided with bulges or inwardly disposed ribs adapted to clcnch the member 10 against the rim 12 in a firm man ner, without any danger of cutting the outer member of the *ire 10, and each ofthe rings l5 has its ends over lapped and provided on their opposing faces with interlocking teeth or notches 1G so that the rings may be compressed circumferentially around the main rim 1,2, the teeth slipping over each other und interlocking in this position," when the desired tensionof the rings 15 is reached. The twoends oi each ring may be secured together by means oi screws 17 or the like.. Each ring 15 is provided at one point with a lug 18 adapted to enter a socket formed for it in the respective flange of the main rim 12, so that the said ring may be tightened by drawing upon one end only.

Freni the foregoing description in connection with the accompanying drawing, it will be seen that I have provided a very simple and eflicient construction of puncture proofltire, in which the inner pneumatic tube is effecth ely protected, while at `the same time the cliaracteristic oi resiliency is retained, the split band 5 yielding by a sliding action of its overlapped ends, when radial stress is imposed upon the wheel, and not flexing as would be the case if the band 5 were endless.

tween said plies, said bund having overlapping.; ends :1nd-

provided with wear strips secured to the opposing faces of said ends, and an outertire section on the outside of said protective covering,

2. A tlre, consisting of :1n inner tube, n protective covering therefor embodying inner and outer plies secured together and an impenetrable spring bund interposed between sald plies, said band having mei-lapping ends und provided with Wear strips secured to the opposing faces of Suid ends, and an outer tire section on the outside of said see protective covering, the said protective covering being pro- 10 vided with a longitudinally extending side sIQt registering with said wear strips, as :1nd for the purpose\sct forth.

In testimony whereof I atx my signature in presence of two Witnesses.
